What are the main characteristics of the atomic absorption mercury meter?

QM201B Atomic Absorption Mercury Meter, which is as good
as the QM201 Fluorescence Mercury Meter.

Complies with JB5228-91 mercury detector department standards
.

The instrument is also called a cold atomic absorption mercury detector on the market
.

It maintains the advantages of easy operation and high sensitivity of our company's traditional mercury detector, in particular, it uses an external reaction bottle, which is easy to clean and has high
reliability.

This is the outstanding advantage
of this instrument.

Due to the use of dual beam light paths, the light source changes cancel each other out, increasing long-term stability
.

The use of single-chip microcomputer to control the solenoid valve automatic switching, the measurement state is closed-loop gas path, the cleaning state is open-loop airway
.

This makes the data stable during measurement and the tubing easy to clean
.

Main features: 1.
Very baseline stability 2.
There is a very short-term and long-term accuracy 3.
2-point calibration, concentration direct reading method can be used 4.
No argon or nitrogen as a carrier gas, suitable for unconditional use of argon and nitrogen working environment 5.
Automatic adjustment
of the gas flow of measurement and cleaning.

The QM201B Atomic Absorption Mercury Meter is a modular design instrument that can be adapted to the different needs
of each laboratory.

Sampling optional: peristaltic pump sampler; Output optional: PC or printer
